The WTA Tour has announced a strategic partnership with CVC Capital Partners which will see the private equity firm invest $150 million (£125 million) into women's tennis.
In return, CVC will take a 20% stake in a newly created company with the working title of WTA Ventures.
The WTA will retain full regulatory and sporting responsibility.
Investment in the women's game is much needed, with prize money continuing to lag behind the men's ATP Tour.
The WTA's finances suffered significantly when CEO Steve Simon suspended all tournaments in China and Hong Kong at the end of 2021.
